read <fname> | ||
Read the priors from a given file. The file <fname> can be a mvg-file, an hmm-file or a simple matrix (vector) containing the (scaled) priors. In case an HMM is read, the average mixture size is set as well (see the lmo command). | ||
set priors <expression> ... | ||
Set the priors to some values. | ||
normalize priors | ||
Normalize the priors so they add up to 1.0 | ||
lmo <log_min_out>(0.0) [av_ngps](1.0) | ||
Set the relative flooring value to avoid zero probs for non evaluated Gaussians. If a non-zero <av_ngps> (average number of Gaussians per state) is given, the LMO is automatically decreased by log2(av_ngps). If an HMM was read before (see the read command) and <av_ngps> is zero, then <av_ngps> is derived from the HMM. | ||
